This visualization presents a horizontal bar chart comparing the top 20 countries by population in 2010. It is built with React and renders SVG elements, using D3.js v5 functions for data processing, specifically `csv`, `scaleBand`, `scaleLinear`, and `max`. The chart displays population values as green bars, with red tick lines on the bottom axis and formatted tick labels converting values to billions. The data is loaded from a remote CSV file and the visualization includes a tooltip showing precise population values on hover.
